NAME
App::Genpass - Quickly and easily create secure passwords
VERSION
version 2.33
SYNOPSIS
use App::Genpass;
my $genpass = App::Genpass->new();
print $genpass->generate, "\n";
$genpass = App::Genpass->new( readable => 0, length => 20 );
print "$_\n" for $genpass->generate(10);
DESCRIPTION
If you've ever needed to create 10 (or even 10,000) passwords on the fly
with varying preferences (lowercase, uppercase, no confusing characters,
special characters, minimum length, etc.), you know it can become a
pretty pesky task.
This module makes it possible to create flexible and secure passwords,
quickly and easily.
use App::Genpass;
my $genpass = App::Genpass->new();
my $single_password = $genpass->generate(1); # returns scalar
my @single_password = $genpass->generate(1); # returns array
my @multiple_passwords = $genpass->generate(10); # returns array again
my $multiple_passwords = $genpass->generate(10); # returns arrayref
This distribution includes a program called genpass, which is a command
line interface to this module. If you need a program that generates
passwords, use genpass.
SUBROUTINES/METHODS
new
Creates a new instance. It gets a lot of options.
new_with_options
Creates a new instance while reading the command line parameters.
parse_opts
Parses the command line options.
configfile
An attribute defining the configuration file that will be used. If one
is not provided, it tries to find one on its own. It checks for a
".genpass.yaml" in your home directory (using File::HomeDir), and then
for "/etc/genpass.yaml".
If one is available, that's what it uses. Otherwise nothing.
You must use the "new_with_options" method described above for this.
flags
These are boolean flags which change the way App::Genpass works.
number
You can decide how many passwords to create. The default is 1.
This can be overridden per *generate* so you can have a default of
30 but in a specific case only generate 2, if that's what you want.
readable
Use only readable characters, excluding confusing characters: "o",
"O", "0", "l", "1", "I", and special characters such as '#', '!',
'%' and other symbols.
You can overwrite what characters are considered unreadable under
"character attributes" below.
Default: on.
verify
Verify that every type of character wanted (lowercase, uppercase,
numerical, specials, etc.) are present in the password. This makes
it just a tad slower, but it guarantees the result. Best keep it on.
To emphasize how "slower" it is: if you create 500 passwords of 500
character length, using "verify" off, will make it faster by 0.1
seconds.
Default: on.
attributes
minlength
The minimum length of password to generate.
Default: 8.
maxlength
The maximum length of password to generate.
Default: 10.
length
Use this if you want to explicitly specify the length of password to
generate.
character attributes
These are the attributes that control the types of characters. One can
change which lowercase characters will be used or whether they will be
used at all, for example.
# only a,b,c,d,e,g will be consdered lowercase and no uppercase at all
my $gp = App::Genpass->new( lowercase => [ 'a' .. 'g' ], uppercase => [] );
lowercase
All lowercase characters, excluding those that are considered
unreadable if the readable flag (described above) is turned on.
Default: [ 'a' .. 'z' ] (not including excluded chars).
uppercase
All uppercase characters, excluding those that are considered
unreadable if the readable flag (described above) is turned on.
Default: [ 'A' .. 'Z' ] (not including excluded chars).
numerical
All numerical characters, excluding those that are considered
unreadable if the readable flag (described above) is turned on.
Default: [ '0' .. '9' ] (not including excluded chars).
unreadable
All characters which are considered (by me) unreadable. You can
change this to what you consider unreadable characters. For example:
my $gp = App::Genpass->new( unreadable => [ qw(jlvV) ] );
After all the characters are set, unreadable characters will be
removed from all sets.
Thus, unreadable characters override all other sets. You can make
unreadable characters not count by using the ">
option, described by the *readable* flag above.
specials
All special characters.
Default: [ '!', '@', '#', '$', '%', '^', '&', '*', '(', ')' ].
(not including excluded chars)
generate
This method generates the password or passwords.
It accepts an optional parameter indicating how many passwords to
generate.
$gp = App::Genpass->new();
my @passwords = $gp->generate(300); # 300 passwords to go
If you do not provide a parameter, it will use the default number of
passwords to generate, defined by the attribute number explained above.
This method tries to be tricky and DWIM (or rather, DWYM). That is, if
you request it to generate only one password and use scalar context
(">), it will return a single password.
However, if you try to generate multiple passwords and use scalar
context (">), it will return an array
reference for the passwords.
Generating passwords with list context (">)
will always return a list of the passwords, even if it's a single
password.
get_config_from_file
Reads the configuration file using Config::Any.
Shamelessly lifted from MooseX::SimpleConfig.
